Answer:
C
Step-by-step explanation:
First, you gotta complete the square!
x^2+12x+36 = (x+6)^2
y^2-12y+36 = (y-6)^2
So, we have (x+12)^2 + (y-6)^2 = -56 + 36 + 36
The right side of the equation is the radius^2.
Simplify:
-56 + 36 + 36 = 16
The square root of 16 is 4, so the answer is C!
It would be 35 because 7x5 equals 35
